There's definitely some truth to that, especially with regard to older Arabs no terminally online. However, it's not like they'll start voting R en masse, more likely is lower turnout and some 3rd party defections.
I generally think the impact of October 7 and its aftermath is vastly overestimated, and just related to Arab Americans, but in general.
2022 suggested a decent number flipping from D to R (or a bunch of new R Arab Americans who hadn't voted before showing up). Pretty sure there's nowhere else in the state where Dixon got more votes than Trump.
In this segment of Dearborn Dixon got outright more votes than Trump as Whitmer got less than half of Biden's vote total.
